Description

Overview

Thermo King X430 Valve Plate O-Ring is an aftermarket replacement for selected Thermo King reciprocating compressor applications. It supports sealing during compressor service, so it helps technicians rebuild or repair the assembly with the correct small sealing part. This O-ring suits valve plate, valve, throttling valve and cylinder sleeve positions on compatible compressors. Because small seals can affect compressor performance, this part suits workshops that service transport refrigeration units regularly.

Compliance and Safety

Follow the correct compressor service procedure when you replace sealing parts in the valve plate area. Also clean the groove, mating surfaces and nearby components before reassembly, because trapped debris can damage the seal and shorten service life. If the compressor is apart for broader repair work, inspect related gaskets and sealing surfaces at the same time so you do not need to strip the assembly again.

Trailer Applications

Thermo King X430 Valve Plate O-Ring suits refrigerated trailer and transport refrigeration maintenance where technicians service reciprocating compressors. It is a practical choice for workshop rebuilds, planned maintenance and breakdown repairs where correct small sealing parts help restore the compressor assembly properly. Thermo King X430 Valve Plate O-Ring also suits jobs where technicians service older unit families that still run the listed compressor models.
